Molecular genotyping of Theileria spp. detected in horses from Corrientes City, Argentina.

After the previous description and characterization of Theileria equi sensu stricto (Genotype A) in Argentina, the aim of the present study was to investigate the possible heterogeneity of 18 S rDNA genotypes circulating in this country. Therefore, blood samples from 18 horses from two different neighborhoods of Corrientes City, Corrientes Province, were analyzed for infection with Theileria species. Theileria DNA was detected in five samples (27.

Evaluation of the transmission of Anaplasma marginale by Amblyomma tonelliae.

This study aimed to evaluate A. marginale transstadial (TST) and transovarial transmission (TOT) by Amblyomma tonelliae through vector competence assays and analysis of natural infection in free-living ticks. This three-host tick species was chosen as model because it is a usual parasite of cattle in all their parasitic stages, making them potential vectors through TST or TOT.

Polyamine-Enriched Exosomes from Drive Host Macrophage Polarization via Immunometabolism Reprogramming.

() promastigotes secrete exosomes that are crucial in host-pathogen interactions and intercellular communication by carrying parasite-specific molecules. Although the composition of cargos in exosomes is known, the effects of the unique metabolic repertoire on immunometabolism rewiring of macrophage polarization are poorly understood. Interestingly, we found the enrichment of polyamines (PAs) such as spermidine and putrescine in the -exosomes.

Temporal trends in organ donation among cardiac arrest patients treated with extracorporeal cardiopulmonary resuscitation.

Aims: This study explores the evolution of organ donation from patients treated with extracorporeal-cardiopulmonary-resuscitation (ECPR) for refractory out-of-hospital-cardiac-arrest (OHCA) and evaluates the public health benefits of a mature ECPR program.

Methods: This retrospective, single-center study included OHCA patients (2016-2023) who had mostly initial shockable rhythms and were treated with ECPR. Organ donation rates from non-survivors through these years were analyzed.

Development and evaluation of a TaqMan® real-time PCR assay for species-specific detection of Ehrlichia canis.

The aim of this work was to develop a real-time PCR assay with a TaqMan® probe that detects a species-specific part of the 16S rDNA gene of Ehrlichia canis. Canine blood samples (n = 207), collected and tested by a conventional PCR assay within a study conducted by De Salvo et al., were simultaneously analyzed with the novel designed real-time PCR, and the results of both assays were compared.

Tirofiban-induced diffuse alveolar haemorrhage.

A middle-aged man presented with inferior wall ST-elevation myocardial infarction and underwent primary percutaneous coronary intervention with tirofiban administered due to extensive thrombus. He developed sudden-onset dyspnoea, bilateral crepitations, haemoptysis, desaturation and hypotension an hour after starting tirofiban infusion. The tirofiban, antiplatelet medications and heparin were stopped immediately.

The link between carotid artery stenosis and outcomes in patients with refractory out-of-hospital cardiac arrest.

Background: Mortality of out-of-hospital cardiac arrest (OHCA) remains high. Extracorporeal cardiopulmonary resuscitation (ECPR) has revolutionized OHCA treatment, but our understanding of the ECPR responder's clinical profile is incomplete. Carotid artery stenosis (CAS) is a well-established cardiovascular disease risk factor.

This regimen achieved a high pathological complete response (ypT0/TisN0) rate of 55.2% and favorable survival outcomes (30-month event-free survival, 91.

Team based collaborative care model, facilitated by mHealth enabled and trained nurses, for management of heart failure with reduced ejection fraction in India (TIME-HF): design and rationale of a parallel group, open label, multi-centric cluster randomised controlled trial.

Heart failure (HF) is a debilitating condition associated with enormous public health burden. Management of HF is complex as it requires care-coordination with different cadres of health care providers. We propose to develop a team based collaborative care model (CCM), facilitated by trained nurses, for management of HF with the support of mHealth and evaluate its acceptability and effectiveness in Indian setting.

Left rib fractures during cardiopulmonary resuscitation are associated with hemodynamic variations in a pig model of cardiac arrest.

Background: Chest compressions (CC) are the cornerstone of cardiopulmonary resuscitation (CPR). But CC are also known to cause injuries, specifically rib fractures. The effects of such fractures have not been examined yet.

Correlation Between Post-Radiosurgery Perinidal Hyperintensity and AVM Obliteration Following LINAC-Based Stereotactic Radiosurgery.

Objective: We studied the correlation between new-onset perinidal hyperintensity (PH) on T2-weighted magnetic resonance imaging and obliteration of intracranial arteriovenous malformation (AVM) after stereotactic radiosurgery (SRS).

Methods: A retrospective study of 148 patients with an intracranial AVM who underwent SRS between September 2005 and June 2018 and had ≥1 radiological follow-up (early magnetic resonance imaging) 12-18 months after SRS was performed to analyze the correlation between PH (graded from 0 to 2) and AVM obliteration.

Results: Of the 148 patients, 95 were male.

Cultivation of carbohydrate-rich microalgae with great settling properties using cooling tower wastewater.

Wastewater treatment and simultaneous production of value-added products with microalgae represent a sustainable alternative. Industrial wastewater, characterized by high C/N molar ratios, can naturally improve the carbohydrate content in microalgae without the need for any external source of carbon while degrading the organic matter, macro-nutrients, and micro-nutrients. This study aimed to understand the treatment, reuse, and valorization mechanisms of real cooling tower wastewater (CWW) from a cement-processing industry mixed with domestic wastewater (DW) to produce microalgal biomass with potential for synthesis of biofuels or other value-added products.

Preliminary Study on Artificial versus Animal-Based Feeding Systems for Ticks (Acari: Ixodidae).

Hard ticks pose a threat to animal and human health. Active life stages need to feed on a vertebrate host in order to complete their life cycle. To study processes such as tick-pathogen interactions or drug efficacy and pharmacokinetics, it is necessary to maintain tick colonies under defined laboratory conditions, typically using laboratory animals.

Feasibility study of total marrow lymphoid irradiation with volumetric modulated arc therapy: clinical implementation in a tertiary care center.

Purpose: Total marrow lymphoid irradiation (TMLI) with volumetric modulated arc therapy (VMAT) is challenging due to large treatment fields with multiple isocenters, field matching at junctions, and targets being surrounded by many organs at risk. This study aimed to describe our methodology for safe dose escalation and accurate dose delivery of TMLI treatment with the VMAT technique based on early experience at our center.

EPS-mediated biosynthesis of nanoparticles by Bacillus stratosphericus A07, their characterization and potential application in azo dye degradation.

Microbial exopolysaccharides (EPS) are biocompatible, biodegradable, and less toxic substances secreted outside the cell. They adsorb metal cations to its surface, making it another captivating property, which helps in stabilizing and biosynthesizing metal nanoparticles. Owing to these properties, we adopted bacterial EPS toward the green synthesis of nanoparticles and its application in the removal of azo dyes.
